[0045] Please refer to Figure 2 , Figure 2Schematic diagram of the exploded structure of the battery 100 provided in some embodiments of the present application. The battery 100 includes a box 101 and a battery cell 102, and the battery cell 102 is contained in the box 101. Among them, the box 101 is the main storage space for the battery cell 102.

The second box 101b may be a hollow structure with one end open, the first box 101a may be a plate-like structure, the first box 101a covers the open side of the second box 101b, so that the first box 101a and the second box 101b together define a storage space; the first box 101a and the second box 101b may also be hollow structures with one side open, the open side of the first box 101a covers the open side of the second box 101b. Of course, the box 101 formed by the first box 101a and the second box 101b may be in a variety of shapes, such as a cylinder or a cuboid. The box 101 is usually made of metal materials, such as steel or aluminum.

[0046] There may be multiple battery cells 102, and the multiple battery cells 102 may be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells 102 are both connected in series and in parallel. The multiple battery cells 102 may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells 102 is accommodated in the box 101. Of course, the battery 100 may also be a battery module formed by connecting multiple battery cells 102 in series, in parallel, or in a mixed connection, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and accommodated in the box 101. The battery 100 may also include other structures. For example, the battery may also include a busbar component for realizing electrical connection between the multiple battery cells 102.

[0047] The battery cell 102 may be a secondary battery or a primary battery, or a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 102 may be cylindrical, flat, rectangular, or in other shapes.

[0048] In some embodiments, the battery 100 also includes a connector 103 at the battery end, and the connector 103 at the battery end is used to connect to an external component. Here, the external component is a connector of an electrical device as an example for explanation. The connector 103 at the battery end is connected to the connector at the electrical device end, and is used to transmit the electrical energy of the battery 100 to the electrical device. In the process of connecting the connector 103 at the battery end and the connector at the electrical device end to transmit electrical energy, heat will be generated between the two connectors. When the heat accumulates at the connection and cannot be dissipated in a timely and effective manner, it will cause the connector to fail and even cause safety hazards.

[0049] Based on this, some embodiments of the present application provide a battery 100, an electrical device and a battery connector 103, wherein a temperature detection element 2 is arranged inside the connector 103 of the battery 100. The temperature detection element 2 can accurately and timely detect the heat generated in the process of connecting the connector 103 of the battery 100 with external components and transmitting electrical energy, so as to be used for early warning and reduce the occurrence of safety hazards.

[0050] refer to Figure 3 In some embodiments, the battery 100 includes a housing 101 , a battery cell 102 , and a connector 103 .

[0051] The battery cell 102 is disposed in the box 101 .

[0052] The connector 103 is provided in the housing 101 and is electrically connected to the battery cell 102. The connector 103 is configured to be connected to an external component. The connector 103 includes a housing 1 and a temperature detection element 2, and the temperature detection element 2 is provided inside the housing 1.

[0053] In some embodiments, the external component may be a connector of an electrical device, and the connector 103 of the battery 100 is connected to the connector of the electrical device to transmit the power of the battery cell 102 to the electrical device, providing operating power or driving power to the electrical device. Alternatively, the external component may also be a connector of another battery 100, and the battery 100 of the present application may be charged through another battery 100.

[0054] In some related technologies, the joint between the connector 103 and the external component is fastened with a connector (e.g., bolt). The connector between the connector 103 and the external component may be insufficiently fastened or loose, which increases the resistance of the joint and generates a large amount of heat. In the event of a fault, there is no early warning or alarm.

[0055] Based on this, in an embodiment of the present application, the connector 103 includes a temperature detection element 2, through which the temperature inside the connector 103 can be detected in time to issue an early warning to remind the operator to take measures to reduce the occurrence of safety hazards.

[0056] In the above-mentioned embodiment of the present application, the temperature detection element 2 is arranged inside the shell 1. Compared with the case where the temperature detection element is arranged outside the shell, the temperature detection element 2 in the embodiment of the present application is closer to the electrical connection position of the male and female pairing of the connector, and is closer to the heating part inside the connector 103. It can more accurately, timely and intuitively give the temperature inside the electrical connection position of the male and female pairing of the connector 103, so as to quickly issue an early warning and reduce the occurrence of safety hazards.

[0057] In the above embodiment, a temperature detection element 2 is set in the connector 103 of the battery 100. The temperature information detected by the temperature detection element 2 can be transmitted to the battery management system 104 of the battery 100. The connection is convenient. The battery management system 104 can quickly determine whether the battery is overheated based on the real-time temperature data provided by the temperature detection element 2, and remind to take corresponding protective measures to prevent safety hazards such as thermal runaway, fire or explosion, and the response is timely and rapid.

[0058] In some embodiments, the temperature detection element 2 includes a temperature sensor.

[0059] In some embodiments, the temperature detection element 2 includes an NTC (Negative Temperature Coefficient) temperature sensor. The NTC temperature sensor has the advantages of high sensitivity, wide temperature range, high stability and reliability.

[0060] In some embodiments, the temperature detection element 2 may use epoxy resin, metal, or glass as the outer shell of the temperature sampling chip.

[0061] In some embodiments, the box 101 includes a first cavity 1011 and a second cavity 1012. The first cavity 1011 is configured to accommodate the battery cell 102, and the second cavity 1012 is configured to accommodate the battery management system 104, high-voltage devices, etc. The battery management system (BMS) is an electronic system for monitoring and managing batteries.

[0062] refer to Figure 4 and Figure 5 In some embodiments, the connector 103 further includes a terminal 3 disposed inside the housing 1 , and the temperature detection element 2 is disposed in close contact with the terminal 3 .

[0063] In the above embodiment, the terminal 3 of the connector 103 is used to transmit electric energy in combination with the terminal of the external component.

[0064] In some embodiments, the terminal 3 is not completely located inside the housing 1 , and the terminal 3 has a portion extending out of the housing 1 .

[0065] In some embodiments, the terminal 3 comprises a metal conductor terminal.

[0066] The terminals of connector 103 are used to transmit electrical energy in combination with terminals of external components. Therefore, the terminal junction of connector 103 is where heat is generated. In some embodiments, temperature detection element 2 is fitted on terminal 3 of connector 103, directly located at the heat-generating part of connector 103, and can detect the temperature of the terminal junction more real-time, accurately and quickly, which is conducive to timely detection of temperature anomalies and improves sampling accuracy and system response speed.

[0067] refer to Figure 6 In some embodiments, the connector 103 further includes a terminal 3 disposed inside the housing 1 , and the temperature detection element 2 is disposed inside the terminal 3 .

[0068] The terminals of connector 103 are used to transmit electrical energy in combination with terminals of external components. Therefore, the terminal junction of connector 103 is a location where heat is generated. In some embodiments, the temperature detection element 2 is arranged inside the terminal 3 of connector 103, directly located at the heating part of connector 103, and can detect the temperature of the terminal junction more real-time, accurately and quickly, which is conducive to timely detection of temperature anomalies and improves the sampling accuracy and system response speed.

[0069] refer to Figure 4 and Figure 5 In some embodiments, a thermal conductive adhesive 6 is filled between the temperature detection element 2 and the terminal 3 .

[0070] Since the temperature detection element 2 and the terminal 3 are closely attached to each other, there is a problem of poor installation stability. In addition, due to the limitations of installation space and withstand voltage insulation requirements, the wire diameter of the wire 21 of the temperature detection element 2 cannot be very large, which may cause the risk of the wire harness falling off.

[0071] Based on this, in order to increase the stability of the wire 21 at the tail of the temperature detection element 2 and reduce the error of temperature conduction, the form of encapsulation of thermal conductive glue is adopted. The use of thermal conductive glue material can not only fill the gap between the temperature detection element 2 and the terminal 3, but also bond the wire 21 at the tail of the temperature detection element 2 to prevent the wire 21 from falling off.

[0072] In some embodiments, the temperature detection element 2 is arranged outside the terminal 3, and the temperature detection element 2 is arranged in close contact with the terminal 3. In order to increase the installation stability of the temperature detection element 2, a thermal conductive adhesive 6 is filled between the temperature detection element 2 and the terminal 3. The use of the thermal conductive adhesive 6 can not only fill the gap between the temperature detection element 2 and the terminal 3 and improve the installation stability of the temperature detection element 2, but also the thermal conductive adhesive 6 can realize efficient heat conduction between the two components. Furthermore, the wire 21 at the tail of the temperature detection element 2 is bonded to prevent the risk of the wire 21 falling off.

[0073] In the above embodiment, the temperature detection element 2 is arranged inside the terminal 3, and the four sides of the temperature detection element 2 are all arranged in contact with the inner wall surface of the terminal 3. In order to increase the installation stability of the temperature detection element 2, a thermal conductive adhesive 6 is filled between the temperature detection element 2 and the inner wall surface of the terminal 3. The use of the thermal conductive adhesive 6 can not only fill the gap between the temperature detection element 2 and the inner wall surface of the terminal 3, thereby improving the installation stability of the temperature detection element 2, but also realize efficient heat conduction between the two components. Furthermore, the thermal conductive adhesive 6 can also bond the wire 21 at the tail of the temperature detection element 2 to prevent the risk of the wire 21 being detached.

[0074] In the above embodiment, the thermal conductive adhesive 6 can bond the surfaces of the two components together and can also transfer heat to achieve efficient heat conduction between the two components.

[0075] refer to Figure 4 and Figure 5 In some embodiments, a groove 4 for accommodating the temperature detection element 2 is provided in the housing 1, and a limiting portion 5 is provided at the open end of the groove 4, which abuts against the temperature detection element 2 to limit the temperature detection element 2 from falling off from the groove 4.

[0076] In the above embodiment, the groove 4 includes an open end and a closed end at the bottom of the groove. The temperature detection element 2 is inserted into the groove 4 from the open end of the groove 4. A limiting portion 5 is provided at the open end of the groove 4. The limiting portion 5 abuts against the temperature detection element 2 to limit the temperature detection element 2 from falling off the groove 4, thereby improving the installation reliability of the temperature detection element 2.

[0077] In some embodiments, the limiting portion 5 extends from the side wall of the open end of the groove 4 to the inside of the groove 4 to form a boss, which abuts against the end of the temperature detection element 2 near the open end of the groove 4 to limit the temperature detection element 2 from falling off from the groove 4.

[0078] In some embodiments, the wire 21 of the temperature detection element 2 extends from the open end of the groove 4 and can be connected to the battery management system 104. The signal detected by the temperature detection element 2 is transmitted to the battery management system 104, and the battery management system 104 is used to determine whether the temperature inside the connector 103 exceeds the standard, whether there is a safety hazard, etc. according to the signal.

[0079] In some embodiments, the connector 103 further includes two terminals 3 disposed inside the housing 1 , and the number of the temperature detection elements 2 is two. The two temperature detection elements 2 detect the temperatures of the two terminals 3 in a one-to-one correspondence.

[0080] In the above embodiment, by respectively setting temperature detection elements 2 on the two terminals 3, the temperature changes at two positions can be monitored simultaneously to provide more comprehensive temperature information, and the two temperature detection elements 2 can independently detect the temperature changes at their respective positions so as to be able to respond quickly to any temperature abnormalities.

[0083] In the above embodiment, the temperature detection element 2 is fitted on the terminal 3 of the connector 103 and is directly located at the heating part of the connector 103. It can detect the temperature at the terminal junction more real-time, accurately and quickly, which is conducive to timely detection of temperature anomalies and improving sampling accuracy and system response speed.

[0084] In some embodiments, the two temperature detection elements 2 are disposed inside the two terminals 3 in a one-to-one correspondence.

[0086] In some embodiments, the two temperature detection elements 2 are disposed on a side where the two terminals 3 are adjacent to each other, or the two temperature detection elements 2 are disposed in a one-to-one correspondence on a side where the two terminals 3 are away from each other.

[0087] In the above embodiment, there is a temperature concentration area between the two terminals 3, and the two temperature detection elements 2 are arranged on the side adjacent to each other of the two terminals 3, which can detect the temperature at the junction of the terminals more accurately and quickly, which is conducive to timely detection of temperature anomalies and improving sampling accuracy and system response speed.

[0088] In the above embodiment, the two temperature detection elements 2 can also be respectively arranged on the side of the two terminals 3 away from each other.
